The 49ers did not claim anyone and instead focused on building their 10-man practice squad, which is expected to include outside linebacker Marcus Rush, who led the NFL with six sacks in the exhibition season.

Driskel got beaten out by Christian Ponder to serve as the 49ers’ No. 3 quarterback behind opening-day starter Blaine Gabbert and No. 2 Colin Kaepernick. Driskel was a sixth-round draft pick who played at Lousiana Tech and Florida.

Driskel flamed out in Thursday’s exhibition finale, having his first two passes intercepted and finishing 1-of-4 for 3 yards. Meanwhile, Ponder, the Minnesota Vikings quarterback from 2011-14, ran for two touchdowns and completed 8-of-14 passes for 101 yards.

Driskel joins a Bengals roster that includes only two other quarterbacks: Andy Dalton and backup A.J. McCarron.

Lemonier, a 2013 third-round drat pick by the 49ers, was one of five players the Browns claimed, including former Raiders running back George Atkinson. Ex-Raiders defensive back Neiko Thorpe went to the Indianapolis Colts.

Two other former 49ers were traded last week rather that outright waived: cornerback Kenneth Acker to the Kansas City Chiefs and safety L.J. McCray to the Seattle Seahawks, both reportedly for compensatory seventh-round draft picks.
